Response Time Item Response Models
Response times and responses can be collected via computer adaptive testing or computer-assisted questioning. Inferences about test takers and test items can therefore be based on the response time and response accuracy information. Response times and responses are used to measure a respondent's speed of working and ability using a multivariate hierarchical item response model. A multivariate multilevel structural population model is de_ned for the person parameters to explain individual and group di_erences given background information. An application is presented that illustrates novel features of the model.
